IMPROVEMENT IN HARVESTER-RAKES.

TO ALL WHOM IT MAY CONCERN: ,i

Bo it known that we, Learner. J. McGonnrcn, WILLIAM R. Benen, and L innnnr EnrnLnINo, all ofl Chicago, in the county oi' Cool-r, and State cf Illinois, have invented certain new and useful Improvements in Harvesters, of which the following is afull, clear, end exact description, reference being had tothe accompanying drawings, which make part of this specification, and'in which- Figure 1 represents a plan or top view of u. harvester to which our improvements cre applied.

Figure 2 represents a view in elevation of the same, es seen from the divider-side looking towards the main frame, with the reel, platform, und cutting-apparatus in section at the'line z x of iig. 1. 4

Figure 3 represents avew, partly in elevation end partly in section, shov1/ing.tlrereeling und rakingapparatus.

The invention herein claimed consists- First,'in u novel method of' combining, in o. harvester, a hinged finger-bendiga narrow, fixed platform attached to the finger-beam,oI dropping-,pletform hinged to the tired oncle reel-support monntedrvou the ngcr- -Tbeamfand supporting, reeling, and raking-devices revolving on a. borizontulhaft.

Second, in a. novel method of constructing the tripping-devices which operate the drepper.

It is obvious that some parts of our invention might be applied to many of the various styles of machines in use, without departing from the spirit ofthe invention. l

The accompanying drawings represent ull our improvements as combined in s. machine for which Letters Patent of the United States, numbered 61,228, and dated January 15, 1867, were grunted to L. J. McCORMICK and L. EBPELDING. l

In this instance, two driving-wheels, A, are shown as mounted'on anfaxle, B, supporting e. main freine, C, from which a tongue, D, projects. A driver's. scat, E, is also mcnnted on this frame. A supplementary frame, F, vibrutes in proper bearings about u counter-skilift, G, driven by proper gearing from the main wheels, und communicating motion to the cutters in :my usual, well-known wey.

.A shoe, K, to which the finger-beam L is secured in the usuel ay, is attached tothe supplementary frame by u. horizontal swivelling-piu, z, passing through a `stirrup, I-Ldepending from the inner rear corner of tho frame, and pivotcd to the heel of the shoe, while the toe is pivoted to un arched brace, I, extending over und pivoted to the stubble-side of' the supplementary frame.

By this mode of attachment, which is not,` however, here claimed to be new, the finger-beam can riso und fell at either end independently of the main frame', and also rock axially on its pivots, to reise or lower the' points of the guards.'

When it is desi-red to hold the supplementary frame and thc heel-end of the finger-benin at u. uniform height from the ground, und yetleave the finger-beam free to rock axially, us well as to rise and fall at its divider-end, the two frames are connected by bolting e rigid bar, J, on the supplementary frame, to a. projecting arm, j, on the inner rear cerner of the main frame. The tingen-beam is provided with s. cutting-apparatus of approved construction. A narrow platform, M, is rigidly secured to the finger-beam in eny proper, wellknown way that will admit of its being conveniently removed und replaced. A dropping-platform, M', is hinged,

at its forward edge, m, to the rear edge of the fixed platform. A suitable divider and guard-board or i`enee,N, is bolted to the finger-beamen that it muy easily he removed when mowing. The rear end of this guard-board extends backward over the dropping-platformthegrain edge of which rises against its lower edge, when lifted, and is thus prevented from rising above that line.' l u A ledge or flange, n, extends the whole length of the guard-board, for upm-pose hereinafter explained. The divider-end of the finger-beam is supported hy a suitablegrain-wheel; such, for instan-oe, as that shown in L. Enrnnnmos patent of October 1, 1861, No. 33,416.

post, O, is securely bolted, in any proper, well-known way, to the shoe, direotly over the iirg'er-bnm. In A order to adjust the tripping of the pointeot the gun-ds, and et the seine time prevent the oscillation of the reel-post backwards and forwards, we attach a brace-bar, P, to`the top of the post, and pivot its other end to the inner front corner of the main frame, and adjust it by means of a socket and set-screw, p, as shown in iig. 1. I A short shaft, Q, inounted in suitable bearings, q, on the post O, supports the rake and reel-arms, and is driven by a sprocket or notched wheel, R, on the main axle between the wheels. An endless chain, R, enciroles this wheel, and a corresponding one, R, on the outer c nd of the shaft Q.

It will be seen by the drawings that by our mode of arranging the parts, the shoe and reel-post are directly l behind the driving-wheel, whichfarrangement diminishes side-draught, and enables u's to drive the reel from the inside of the inner driving-wheel.

Arms S, arranged tangentially around the shaft Q, carry beaters or ribs S', which sweep over the platform in thehusual way. These ribs, it will be observed, are all arranged on one side of the shaft, while an arm, T, A

carrying a rake-head, T', is arranged on the other side. The rake-arm is also arranged tangentially to the shaft, and the rake revolves in a path concentric with but outside of that of the heaters S', but all revolve in a xed relation to the shaft Q. A projection, t, on the rake, travels on the flange n of the guard-board when raking o, and thus prevents the rake-teeth from striking into the guards as the rake passes over them.

An arm, m', ou the stubble-side of the platform, is connected, by a link-rod, u, with an oscillating lever, U, pivoted to play vertically on the reel-post, and carrying a swvelled dog, 1.1,' which embraces a pam, V, on the shaft Q, and thus drops the platform at stated intervals, as hereinafter explained.

The operation is as follows:

As the machine advances, the heaters S"press the grain backwards upon the platform in the usual way. When the rake-comes round, it sweepsthe gavel back upon the drcpper-platiorm, its sweep extending as far back as the rear edge thereof. As the gavel is swept back, the platform M drops by its own weight, when the lever U enters the recess in the cam V, and the gevel slides upon the ground. As soon as the gavel is discharged, the cam 'V lifts the platform, and holds it up untilthe next discharge takes place.

What we claim as our invention, and desire to secure by Letters Patent, is

1. The combination in va harvester, substantially as set forth, of a hngednger-beam, anarrow platform affixed to the finger-beam, anda dropping-platform hinged to the fixed one, with 'a series of reel-ribs, and a rake revolving over the 4platform on a horizontal shaft, and mounted on a support secured on the shoe.

2. The combination, substantially as setrforth, withthe tripping-cam, of the vibrating-arm U, and oscillatingdog, for the purposes set forth. v

In testimony whereof, we have hereunto subscribed oui names.
